摘  要：
选用2.5%高渗吡虫啉EC、81%辛硫磷EC等5种药剂在小麦抽穗期喷雾,以筛选防治麦红吸浆虫的适宜药剂;选用辛硫磷和吡虫啉在小麦挑旗期、抽穗期、扬花期、抽穗期+扬花期施药,以明确麦红吸浆虫的防治适期。结果表明:小麦抽穗期喷雾以2.5%高渗吡虫啉EC防治效果最好,虫口减退率达到89.45%,其次是81%辛硫磷EC和40%毒死蜱EC(74.50%、71.05%)。不同施药时期防治试验结果显示,以2.5%高渗吡虫啉EC抽穗期+扬花期2次施药效果最好,虫口减退率达95.64%,其次是吡虫啉抽穗期1次施药和81%辛硫磷EC抽穗期+扬花期2次施药。因此,在麦红吸浆虫出土整齐时,选用吡虫啉在小麦抽穗期1次施药防治成虫较为简便有效;在麦红吸浆虫出土不整齐时,可以选吡虫啉或辛硫磷在抽穗期和扬花期2次施药。

摘  要：
Five pesticides were employed to spray on wheat in the tassel period in a field experiment for selecting the optimal pesticide to control Sitodiplosis mosellana.The phoxim and imiadacloprid were applied in the period before emerge,tassel period,flowering period and tassel period + flowering period of wheat to determine the optimal control period.The results showed that among the 5 different pesticides,2.5% imiadacloprid EC got the best effect against Sitodiplosis mosellana and its control effect was up to 89.45%,followed by 81% phoxim EC and 40% chlorpyrifos EC,of which the control effects respectively reached 74.50% and 71.05%.As to different spray periods,two sprays of 2.5% imiadacloprid EC in the tassel period+ flowering period showed the best effect,up to 95.64%,followed by one spray of imiadacloprid in the tassel period and two sprays of 81% phoxim EC in tassel period+flowering period.As a balanced control solution considering the effect and the cost,one spray of imiadacloprid in the tassel period of wheat is the first choice for simple and effective control of Sitodiplosis mosellana if it is neatly unearthed;However,when Sitodiplosis mosellana is irregularly unearthed,the phoxim and imiadacloprid could be applied twice in the tassel period + flowering period of wheat.
